Description

Technical Field

[0001] This utility model relates to copper busbar bending technology, specifically a bending and positioning device for copper busbar processing. Background Technology

[0002] With increasing environmental awareness and the continuous development of new energy technologies, new energy vehicles are gradually becoming more widespread as an environmentally friendly and energy-saving mode of transportation. Flexible copper busbars offer advantages such as high current carrying capacity, low resistance, good flexibility, stress relief, easy installation, and aesthetically pleasing wiring, and are widely used in fields such as power batteries for new energy vehicles.

[0003] The commonly used copper busbar bending and positioning fixtures are mostly produced by special molds customized according to the product. However, there are many types of copper busbar sizes. When switching to different types of copper busbar bending processing, special molds need to be redesigned, which results in high mold production costs and long processing cycles.

It uses inserts to form the lower mold core, and can add or remove inserts according to the size of the copper busbar, without the need to redesign the mold, thus saving mold production time and costs.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a bending and positioning device for copper busbar processing, comprising an upper mold and a lower mold that cooperate with each other. The lower mold includes a lower mold base and a lower mold core. The lower mold core includes a forming part composed of a plurality of forming inserts. A forming block is provided in the middle of the forming insert. The top of the forming block is provided with two mutually perpendicular forming surfaces. A top block is provided on one of the forming surfaces. The top block is used to support the end of the copper busbar.

The upper mold core is fixed below the upper mold base, and the bottom of the upper mold core is provided with a forming groove that cooperates with the forming block. The forming block cooperates with the forming groove to bend and form a copper busbar.

[0007] Preferably, upper pressing blocks are provided on both sides of the upper mold core, and lower pressing blocks are provided on both sides of the lower mold core, with the upper pressing blocks corresponding to the lower pressing blocks.

[0008] Preferably, the lower pressing block is provided with a guide hole, and the upper pressing block is provided with a guide pin, the guide pin being inserted into the guide hole.

[0009] Preferably, positioning inserts are provided on both sides of the forming part, and a positioning block is provided on the top of the positioning insert facing the copper busbar, and the positioning block is used to limit the copper busbar.

[0010] Preferably, the height of both the positioning block and the top block is less than the thickness of the copper busbar.

[0011] In summary, this utility model achieves the following technical effects:

[0012] The bending and positioning device for copper busbar processing of this utility model adopts forming inserts to form the lower mold core. The inserts can be added or removed according to the size of the copper busbar, without the need to redesign the mold, saving mold production time and cost.

[0022] Example 1:

[0023] like Figure 1 As shown in Figure 2, a bending and positioning device for processing copper busbar 7 includes an upper die and a lower die that cooperate with each other. The lower die includes a lower die base 4 and a lower die core 5. The lower die core 5 includes a forming part composed of a plurality of forming inserts 51. A forming block 52 is provided in the middle of the forming insert 51. The top of the forming block 52 is provided with two mutually perpendicular forming surfaces. A top block 53 is provided on one of the forming surfaces. The top block 53 is used to support the end of the copper busbar 7. Positioning inserts 55 are provided on both sides of the forming part. A positioning block 56 is provided on the top of the positioning insert 55 facing the copper busbar 7. The positioning block 56 is used to limit the copper busbar 7. Fixing parts are provided on both sides of the forming insert 51. The fixing parts are provided with pins. The pins are inserted into pin holes 9 so that the forming insert 51 is fixed to the lower die base 4.

[0024] The bending and positioning device for processing copper busbar 7 in this embodiment uses forming inserts 51 to form the lower mold core 5. The inserts can be added or removed according to the size changes of the copper busbar 7 without redesigning the mold, saving mold production time and cost. Moreover, in conjunction with the positioning inserts 55 and the top block 53, the position of the copper busbar 7 can be limited to prevent the copper busbar 7 from tilting during bending, thus ensuring the bending quality of the copper busbar 7.

[0025] The upper mold includes an upper mold base 1 and an upper mold core 2. The upper mold core 2 is fixed below the upper mold base 1. The bottom of the upper mold core 2 is provided with a forming groove that cooperates with the forming block 52. The forming block 52 cooperates with the forming groove to bend and form the copper busbar 7.

[0026] The upper mold core 2 is provided with upper pressure blocks 3 on both sides, and the lower mold core 5 is provided with lower pressure blocks 6 on both sides. The upper pressure blocks 3 and lower pressure blocks 6 correspond to each other. The lower pressure blocks 6 are provided with guide holes 8, and the upper pressure blocks 3 are provided with guide pins. The guide pins are inserted into the guide holes 8. The height of the upper pressure blocks 3 and lower pressure blocks 6 is used to control the gap between the upper mold core 2 and the lower mold core 5 so that it is consistent with the thickness of the copper busbar 7. The setting of the guide pins and guide holes 8 can make the upper mold and the lower mold close accurately.

[0027] The heights of both the positioning block 56 and the top block 53 are less than the thickness of the copper busbar 7.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
